Yamaha Pro Series Prop, 23 Pitch, with Mercury Hub (will work on a Yamaha or Merc). This prop was puchased new and worked by Rich Boger (www.bogerprops.com). I used this on a 21 Cajun Dual Console Bass Boat with a Yamaha 175 on it. The prop after Boger got done with it was remarkably improved – better lift, holeshot and speed. Boger also hubbed it for a Merc. The prop does have some rash on the edges from getting into some gravel once – but I was not able to notice any performance decrease after that. Selling because the boat I had it for was wrecked on the road and wont work on my Pantera Classic.$250 or trade for a Tempest Plus 25PEmail charlie@beachnetservices.comPic1Pic2Pic3
